User blog comment:LegionZero/Nero's Parallels to Vergil and Sparda/@comment-72.218.90.59-20140905202554/@comment-6769189-20140905212244

Dante and Vergil were 19 in DMC3. Yes, but DMC4 is only 10 years later, as stated by the devs themselves

Yes he is of Spardas blood, that is a fact. But there is no evidence to suggest its directly through the twins.

Rebellion was always a representation of Dantes power. He didnt make it his own it always was his own. Like how Bakusaiga came from and represents Sesshomaru. Vergil and Yamato have a relationship like Inuyasha and Tessaiga before Inuyashas fang was added to it. Or Sesshomaru and Tokijin
